This study explores deriving minimal features for a robotic face to convey information (via facial expressions) that people can perceive and understand. Recent research in computer vision has shown that a small number of moving points/lines can be used to capture the majority of information (~95%) in human facial expressions. Here, we apply such findings to(More)

OBJECTIVE In the modern healthcare system, rapidly expanding costs/complexity, the growing myriad of treatment options, and exploding information streams that often do not effectively reach the front lines hinder the ability to choose optimal treatment decisions over time. The goal in this paper is to develop a general purpose (non-disease-specific)(More)
We evaluated the seal-like robot PARO in the context of multi-sensory behavioral therapy in a local nursing home. Participants were 10 elderly nursing home residents with varying levels of dementia. We report three principle findings from our observations of interactions between the residents, PARO, and a therapist during seven weekly therapy sessions.(More)
This paper presents an ongoing project using participatory design methods to develop design concepts for socially assistive robots (SARs) with older adults diagnosed with depression and co-occurring physical illness. We frame SARs development in the context of preventive patient-centered healthcare, which empowers patients as the primary drivers of health(More)
In this paper, we argue that cultural robotics should be grounded in a critical approach that acknowledges the co-construction of culture and scientific practice and technology design, as well as the dynamic nature of culture and its role in shaping human cognition and social interaction. We suggest this can be done in two ways: 1) by making the robot(More)
Mitochondrial hypervariable region I genetic data from ancient populations at two sites in Asia-Linzi in Shandong (northern China) and Egyin Gol in Mongolia-were reanalyzed to detect population affinities. Data from 51 modern populations were used to generate distance measures (Fst's) to the two ancient populations. The tests first analyzed relationships at(More)
The effects of culture and context on perceptions of robotic facial expressions. Abstract 2 We report two experimental studies of human perceptions of robotic facial expressions while 3 systematically varying context effects and the cultural background of subjects (n=93). Except for 4 Fear, East Asian and Western subjects were not significantly different in(More)
